Host Device Print Job Notification with Thumbnail Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in distinguishing between multiple print jobs for the same or similar files, making it hard to recognize which print job an image forming apparatus is performing, leading to resource wastage and potential issues.
Innovation Solution
Incorporating a thumbnail image of the document to be printed into notification information displayed by the host device, allowing users to cancel print commands before the image forming apparatus performs the job, thereby saving resources and enabling real-time monitoring and control of print jobs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only print job name is displayed in notification information, then notification information is simple and easy to display, but users cannot precisely identify which print job is being performed
Solution Approach 1:
The patent uses a thumbnail image (a reduced-size copy) of the document to be printed instead of displaying the full document. This thumbnail copy provides sufficient visual information for users to identify the print job without requiring the complete document content, thus resolving the contradiction between identification accuracy and information complexity.
2Loss of substance
If users cannot identify print jobs precisely, then notification display is simple, but resource wastage occurs due to inability to cancel print commands
Solution Approach 1:
The patent displays the thumbnail image in the notification information before the print job actually executes. This preliminary visual information allows users to identify the document and cancel the print command if necessary, preventing resource wastage from occurring in the first place rather than addressing it after resources are consumed.
3Ease of operation
If thumbnail image is added to notification information, then users can identify and manage print jobs precisely, but notification information becomes more complex
Solution Approach 1:
The patent employs a thumbnail image (a simplified visual copy) that captures essential document characteristics without requiring full document display. This approach enhances ease of operation by enabling precise print job identification while minimizing the increase in notification complexity, as the thumbnail is a condensed representation rather than complete document content.

AI summary
An example host device includes an input/output device to receive, from a user, a print command for a content, a processor, and a memory to store instructions executable by the processor. By executing the instructions, the processor is to generate a print job corresponding to the content, a thumbnail image corresponding to the print job, and a notification banner including the thumbnail image and information about the print job, and control the input/output device to output the notification banner.
